Forest engineer Ivan fell in love with scientist Julie. After their wedding, they bought a guesthouse in the heart of the picturesque Šumava Mountains, where they moved in with Julie's 16-year-old daughter Kačka and her dachshund Hugo. However, Ivan and Julie are primarily focused on having a child and neglect the running of the guesthouse. Julie falls into despair and begins visiting the charlatan Kallvíni, who is supposed to help her get pregnant. It is therefore no surprise that crowds of guests are not flocking to their guesthouse when no one knows about this beautiful place. In addition, the guesthouse is run by two incompetent old women whom Julie hired to help out. Fortunately, her daughter Kačka, who had ADHD as a child and has been listening to her Hugo ever since, comes up with the idea of running a "Guesthouse for dogs... and their owners" with her four-legged friend.
